* Learning how to deal with different materials:
* Mat board
* Corrugated Cardboard
* Foam core
* Acrylic
* Glass
- * Setting up Corel Draw to vector cut / vector engrave / raster
+ * Setting up Inkscape to vector cut / vector engrave / raster
* Download laser-able objects from Thingiverse
===Cost===
$40 per student.
===Duration===
- One day, one hour course
+ One day, four hour course
===Class Size===
- Number of students depends on classroom space, possibly 10-20 students.
+ Class size is limited to 4 students.
===Prerequisites===
- Basic electronic theory will be helpful, although there will be a review.
+ There are no prerequisites.
===Further Information===
See the laser cutter [[materials]] page for general information.
The basic class provides an overview of the machine itself, what materials you can and can&#039;t use, and basics of operation.
You will be provided (3) 6x6&quot; (roughly) pieces of material: poster paper, plywood, and acrylic. The poster paper and acrylic are utilized in two exercises during class time, and the wood is left for you to experiment with on your own.

+ ===== Laser Cutter =====
10BitWorks owns a Rabbit Laser QX-1290-80, an 80 Watt CO2 laser cutter. It is capable of cutting, engraving, and marking a number of different materials quickly and accurately. In the fall of 2014 10BitWorks ran a fundraiser for %%$%%12,000 to purchase the laser cutter. The fundraiser was successful and allowed us to have an operational laser cutter by early December.
==== Rabbit Laser Cutter ====
Inside the laser cutter there is a very powerful CO2 infrared laser that is bounced off of a few mirrors and is finally directed towards the material being cut or etched by a moving mirror and lens that aims the focused beam. These mirrors and lenses are gold coated to provide the best possible transmission of infrared energy.

+ ====== Materials ======
There are a wide range of materials that the Laser Cutter can cut, etch or mark - but some simply don&#039;t work (eg metals) and some are extremely hazardous to either humans or the machine itself (eg PVC and ABS). It is therefore imperative that you check these lists before attempting to cut materials that you have not worked with before.
It is not always obvious which materials will work - for example: Polycarbonate/Lexan produces flames and lethal chlorine gas which will rapidly corrode this %%$%%14,000 machine into uselessness and which is extremely hazardous to the health of people nearby. Yet Acrylic - which looks, smells, feels and tastes just like Lexan - cuts smoothly and cleanly and is one of the best materials to use with the laser! So check and double-check what you&#039;re cutting.

===Wood===
Hobby Lobby, Michaels sell decent birch plywood. The problem with wood from Home Depot and Lowes is that it typically is warped, has more knots, holes, and glue fills all of which cause problems. There are also a number of furniture quality lumber stores in town.
